AI-Powered supplier vetting

SummaryThe supplier is identified as a limited company and trading company offering nutraceutical, pharmaceutical-related, plant-extract, and other products. It reports 50 qualified service-capable suppliers, documented service, corrective-action, preventive-action, and complaint-handling procedures, and finished-product inspection instructions that are uniformly followed. R&D-related evidence includes new products within the past year, ODM services, OEM services for well-known brands, and broad customization options, but no 3D software design service or SDK availability. Stated annual productivity covers NMN, Coenzyme Q10, Resveratrol, and Clobetasol propionate, while the supplier’s product scope includes several additional products. A BV audit is recorded with a report period from May 6, 2025 to May 5, 2026, but the audit result is recorded as “0” without an explanation. No sufficient evidence establishes certification holding, financial credibility, or specific customer cases.

Supplier typeThe supplier is explicitly classified as a trading company and a limited company. Its stated offerings include nutraceutical and related products such as Melatonin, Glutathione, Coenzyme Q10, NMN, and others, and the English company name is Xi'an Tian Guangyuan Biotech Co., Ltd.

After-Sales capabilityThe supplier reports a clear procedure and followed records for handling customer complaints effectively. It also reports written procedures and records for assessing service capability, plus a clear corrective and preventive action mechanism with implementation records, providing explicit evidence of structured service follow-up.

R&D capabilityThe supplier reports new products during the past year, provides ODM services, and describes an R&D and analysis/testing center. However, it does not provide 3D software design services and has no available SDK, so the evidence supports product-development activity but not all forms of technical innovation capability.

Production capacityReported annual productivity is 1 ton of NMN, 5 tons of Coenzyme Q10, 10 tons of Resveratrol, and 0.8 tons of Clobetasol propionate. The supplier also lists multiple products in scope and states that finished products are inspected using instructions that are uniformly followed, demonstrating stated production and inspection capability for the listed items.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. These options are reported consistently across the R&D and design-capability information, indicating broad customization support, although 3D software design is not provided.
